Cullen was an early mover. He was crawling at five months, and walking by nine. Because of this, I felt like I got kind of jipped out of some extra baby months. While other moms still had baby lumps they could sit and shake toys at while they sipped their coffee, I was running around hiding cords, elevating breakables, and throwing my body across the open top of our staircase. We realized pretty quickly that we needed to do some serious babyproofing.
